Microfluidic chips

Our customized microfluidic glass chips are manufactured in cleanroom thanks to a photolitography process coupled to a wet etching in a HF based solution.

Moreover, our glass microfluidics chips are sealed thanks to a low-thermal bonding process, with temperatures below 300°C. This process was developed and patented during the PhD thesis of Clément Nanteuil, the CEO of Klearia, in 2010.

The Advantages of Klearia process for custom glass microfluidics chips manufacturing


Customization and quality of features

Coupling photolitography with wet etching process offer a large range of design's customization with an ideal  roughness and flatness for applications requiring optical observations through a microscope like life sciences for example.


Sensitive materials embedment

Lower temperatures reduce the risk of damaging sensitive materials or components embedded within the chips, making the process suitable for a wide range of applications involving sensors and actuators. Ideal for the manufacturing of Lab-on-chips.


Reduce your development costs

Due to the complex manufactruing steps realized in cleanroom, glass microfluidics chips are generally high entry costs. In Klearia, we propose to manufacture on a 4'' wafer process line in order to reduce the N.R.E on a new design to test. Ideal for small to mdium volume size!

Characteristics of Glass microfluidics chips

Glass chips have the advantage of withstanding extreme conditions: they are resistant to chemicals, and have higher bulging pressures than conventional polymer microfluidic chips. Moreover, their lifespan is considerably longer compared to almost single-use PDMS microfluidic chips (Polydimethylsiloxane).

Microfluidic PDMS Chips

The low entry cost and the fast protoyping capabilities make them interesting to use. Regardless, the lifespan of PDMS chips is short.

Microfluidic Chips can be used with our Pandeno

Our range of microfluidic services is extensive, encompassing everything from the creation of microfluidic chips, to the customization of microfluidic devices or sensors, as well as providing comprehensive R&D support.

The microfluidic device Pandeno is equipped with microfluidic pumps and can be accompanied by solenoid valve modules or flow sensors to best suit your microfluidic circuits.
